Smackover is out of business - but the board is still running...
I found a reference to the oil light sensor being "set to low" and not being an issue. I wonder if another sensor can be used in it's place - like one off a DRZ400 maybe? Either way - it's nothing to worry about - or try running a 20w50 weight oil.

Look at item #4 -
4: Low oil pressure light comes on when the bike is hot & at idle.
I have been assured that the bike is getting enough oil at idle, but the oil pressure sensor setting is too high. No news whether Gas Gas intend to adress this issue, as I'm told it is common.
